The effect of pH value on gold extraction for various ore types is shown in Figure Greatly increasing pH value has a beneficial effect on gold extraction for both oxide and sulfide ores and stabilizes ∼pH whereas for some carbonaceous ores pH value has no apparent effect. However the outcome will vary depending on the
If the solution is rich enough can be treated by zinc powder and the precipitated obtained (cement) obtained will be sent to retorting and smelting. For gold extraction the strength of cyanide solution ranges from to . Lime is added to the process in order to have a pH near to 1011.
May 31 2022By Travis Thornton May 31 2022. A process called "Cyanidation" or cyanide leaching has been the dominant gold extraction technology since the 1970s. In this process sodium cyanide in a dilute solution of ranging from 100 ppm to 500 ppm or to cyanide is used to selectively dissolve gold from ore.
The leaching process showed that the highest percent gold extraction data of was obtained in experiments with 1000 ppm sodium cyanide concentration 10 solids percent and 104149µm grain
